Struct scroll_ring::Buffer

pub struct Buffer<const N: usize> { /* private fields */ }

A very simple implementation of the infinilog buffer.

See module level documentation on its general properties.

Implementations

impl<const N: usize> Buffer<N>

pub fn read_earliest( &self, outbuf: &mut [u8] ) -> Result<(Wrapping<u32>, usize), BufferUnavailable>

Read the earliest available data into outbuf. On success, returns the cursor position corresponding to the start of outbuf, and the number of bytes available (which is the number of bytes copied into outbuf unless it exceeds its size).

pub fn read_from_cursor( &self, cursor: Wrapping<u32>, outbuf: &mut [u8] ) -> Result<usize, ReadErr>

pub fn write(&self, data: &[u8])

Trait Implementations

impl<const N: usize> Default for Buffer<N>

fn default() -> Buffer<N>

Returns the “default value” for a type.
